60. Detect Alternating Pattern

#include <stdio.h>

int is_alternating_pattern(int *mem, int k) {
    int first = *(mem);
    int second;

    if(first) second = 0;
    else second = 1;

    for(int i = 0; i < k; i++){
        if( (i % 2 == 0) && (*(mem + i) != first) ) return 0;
        else if( (i % 2 != 0) && (*(mem + i) != second) ) return 0;
        else continue;
    }
    return 1;
}

int main() {
    int n, k, arr[100];
    scanf("%d %d", &n, &k);

    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }

    int res = is_alternating_pattern(arr, k);
    printf("%d", res);

    return 0;
}
